Princess Tutu

The first season was broadcast in Japan in 2002 and the second in 2004 . It was also adapted into a two-volume manga . Both the manga and anime series were licensed by ADV Films in 2004 for distribution in North America . The series explores the concepts of fate and free will . Reviewers point out that although Princess Tutu is nominally a magical girl series, it is more of a "fairy tale set to ballet with a few magical girl elements mixed in," and its use of dance in lieu of violence to solve conflicts carries "surprisingly effective emotional appeal ."
